Specification of Letters Patent.

Patent-ed oct. 10, 1916.

Application led October 25, 1909. `Seria1No. 524,362.

To ZZ whom t iii-uy concern Be it known that l, GEORGE Jones Fine GUsoN, a subject of the King oi Great Britain, residing at St. Louis, State oi Missouri, have invented a new and useful Valve, ot which the following is a specification.

My invention is particularly designed for service in connection with heating systems; but it is also adapted for general use in which a self-packed, quick opening and closing valve is required.

My valve includes improvements in valves consisting in limiting the valve to tivo positions, and in which the pressure fluid travels in both directions, or wherein the pressure. {iuid is stored on the outlet, or inlet side of the valve, or for purposes in which the outlet is always open to the atmosphere, and particularly for purposes wherein a quick opening and closing of the valve is necessary or desirable.

The objects of my invention are to provide a device `wherein the movement of the valve is restricted to a full Wide open position, and a tight closed posi tion; there being no intermediate station at which the valve can be placed; and having a self-packed stem in both the open and A closed positions; a valve that can not be im# perfectly closed; and its operation and construction prevents thin leaks of steam that cut, or burn, the valve seats; a valve provid ing a return by-pass to carry back to the supply pipe all accumulations of Water in the radiator from the condensed steam, this usually results from imperfectly closed valves, and frequently causes great damage when such condensation is blown out by vvay of the vent valve, and this by-pass is closed against steam entering the radiator by the float cheek valve. The valve is held tightly to its seatby the closing spring and also by the pressure when it travels in the direction to close the valve. The valve is self-closing, and self-packinv, by disengaging the locking device that holds it open; and it is opened, or closed instantly by a single movement of the treadle lever either up or down. The valve casing is provided with a large inlet opening in order that a valve of large area can be employed to reduce the traverse of the valve by increasing its area, and that of the inlet opening. The

large inlet opening is threaded for a large pipe, and is partly closed by a bushing to lit smaller pipes, in yorder toY reduce the number of sizes of valves required to be kept in stock by dealers; and when my valve is used on radiators I provide the upper outlet passage of reduced size to admit steam, or hot Water, and a return lower passage for the Water of condensation, or cooled water, this return bypass being controlled by a floating check valve.

I attain these objects by the mechanism illustrated in the accompanying drawings. in Whichi Figure l, is a view of the valve in vertical section, and in its closed position. Fig.

2, is a vertical sectional view of a'slightly modilied form and on a slightly reduced scale, in its open position, and adapted for general purposes.

Similar numbered reference characters refer to like parts throughout the specification and drawings.

My valve consists of the casing 1, having the enlarged inlet opening to admit the valve 3, and this inlet opening being screwthreaded to fit the reducing bushing 2; the internal opening in this lbushing 2 being made in several different sizes to it any usual size of pipe in a heating plant, and of course the valve casing Will have the thread to fit the largest size of pipe capable of use with the valve; therefore a feiv sizes of my valve Will be capable for` all sizes of pipe used in aheating system. This overcomes the diiiiculty for outlying stores, or coun try dealers, to keep a i'ull supply of valves,

to' fit all sizes of pipe.V

The sliding valve 3 can be constructed on any ot' the Well knoivn plans, it need not be made integral with the stem 4:, as shown, but in any case it Will be applied by Way of the large inlet opening described above; still for some puposes, as for instance when vthe pressure yfluid travels in the opposite di rection, it may then be applied through the openlng closed by the cap-nut when `it Will be opened by an upward movement ini stead of the downward motion as shown in projecting stem 4, which passes through and is guided in the capnut 5, that closes the top opening 1n the valve casing 1. The

stem 4 is Slotted at its apex, or a separate fork may be provided, .or any equivalent ing packing abutment .25, adapted to seat the collar 21, attached to the valve stem 4 and secures a self-packed joint when the valve 3 is in its open position,I (Fig. 2).-l The stem 4 is also equipped with the abutment packing seat 6, adapted to retain the compressible abutment'packing 22, which engages the seat 23, on the'cap-nut 5, in the closed position of the valve 3, and effects a tight joint to retain stored pressure fluid at the outlet end of the valve casing l, (Fig. 1.).

The valve 3 is shown as being integral with the stem 4, but it can be made detachable, and in any of the many plans in service for many years. In either case it is equipped with the 4cornpressible seat 10, which in the closed position, as shown in Fig. 1, rests upon the seat 11, formed on the casing 1. The seat 11, consists of an nnular ridge with a rounded bearing surace.

The valve 3, is shown installed to open downward; but the seat 11 may be formed on the upper surface of the valve casing 1,

when the valve 3 will open upward.

As previously described the valve 3, and

its' attached stem 4, are applied through the large inlet opening in the bottom of the valve'casing 1, and the valve 3, by means of its stem 4, which is movably connected to the treadle lever 7, is moved down by manual pressure on the treadle lever 7 to its wide open position, as shown in Fig. 2. A passage from the steam supply pipe or other connection secured in the bushing 2, or attached directly into the valve casing 1, permits the fluid pressure to pass into the chamber and passage 29, which may when used as a radiator valve, be reduced to a nozzle at 28, to increase the velocity of the heating medium into the radiator, or other receptacle requiring quick heating. Experiment has proven that the quick heating of a radiator is greatly accelerated by a contracted outlet from the radiator valve, but this nozzle construction requires that a return by-pass 30, be provided having the outlet 34, above the floating check valve 8 made of buoyant material, to return the water of condensation back into the valve casing at 33, below the valve 3. This construction will keep the radiator free of condensation and'prevent any discharge of water at the vent valve, by continually draining the radiator. .As the Weight of the water of condentreadle lever 7; but a pivoted fork or equivalent member is Within the plan of such connection to the valve stem 4. The valve stem 4, and the attached valve 3, is moved down to open said valve 3, the opening being effected by the engagement of the stem 4` vwith the treadle lever 7, which is jointed at 20 to the swivel ring 19, that surrounds the valve casing 1, and is held in place by ilanges on the cap-nut 5, and on the valve casing 1. The treadle `lever 7 passes up and over the apex of the valve stem 4, and through the slot therein, or equivalent structure; it then passes down on the opposite side of the valve casing 1, and its lower end is bent into a convenient shape to provide a foot treadle 9, or handle, so that the treadle lever 7, the valve stem 4 and the attached valve 3 can easily be operated .by placing-'a foot upon the treadle and bearing down and depressing the stein 4 and the valve 3, (the stem 4 need not be attached integral to the valve 3, they may be separate parts;) and when the treadle lever 7 is depressed the hook, or clevis 12, which also hinged at 18 to the swivel ring 19, will tilt onto the inclined surface l5 of the recess 13 in the treadle lever 7, and'hold it and the stem 4 and the valve 3 in their wide open position. The purpose of the swivel ring is to enable the foot treadle--9 to be placed in any position for convenience, or to be out of the way.

In every form of my valve the closure is effected by the closing spring 14, which rests upon the valve casing 1 above the valve seat '11, while the upper end of the spring 14 is secured below the collar 6 attached to the stein 4, therefore the spring 14 is'compressed by bearing down upon the foot treadle 9, and the release of the-foot treadle 9 and of the hook or clevis 12 renders the closure of the valve 3 automatic bythe reflex action of the spring 14. The spring 14, may be applied outside of the valve casing 1 above the unite to render a self-packed stem practical and durable as the valve 3 isJrestITicted to a wide open and tight closed position, and is closed automatically by the spring 14.

A hand lever may be substituted for the treadle lever 7, and in some instances both may be desirable.

The structural form of myI valve casing permits the use of a very large valve 3, consequently the opening traverse can be short. This short travel will enable the practical use of an abutting diaphragm packing on the valve stem 4:; and l consider that the use of an abutting diaphragm packing as being within the scope of my invention, and as being an equivalent of the abutment packing seats 22 and 25, as described; also the independent return passage 30 for the Water of condensation justifies a very short traverse of the valve 3, and enables the use of an abutting diaphragm packing.

The structural form of my valve renders it possible to use many parts of an old style valve in remodeling it into my improved structure. To do this I may revise the old valve body, this will place the present valve seat at the bottom, or under side of the valve casing, the old compression nut can be changed into my cap-nut 5, and the old stem and valve may be remodeled to greatly reduce the cost of reconstruction.
